Paper Title:
Wavelet Based Progressive Compression and Transmission of 3D Object
  Abstract

A novel algorithm of progressive compression and transmission based on wavelet transform is proposed in this paper, which deals with the connectivity of the original mesh and consequently reconstructs the basic topological relations of base mesh. Not only the spatial correlations between different levels of details but also the time correlations are exploited to enhance the compression ratio. A concept of ‘frame’, which represents different levels of details at different time, is introduced, and compression mode of ‘F+3D’ (a 3D mesh within a temporal frame) is then achieved. The temporal correlations among frames at different time will be decreased by using a temporal-based lifting wavelet. Then, geometry details in a frame will be translated into several wavelet coefficients which will be joined into the bit stream after being quantized and encoded. Experimental results suggest that the algorithm achieve a good compression ratio for larger 3D models, and the performance in the process of progressive decoding and rendering is satisfied.
